> Partition columns are logical entities that are meant to be consumed by group scan. Currently
ParquetScanBatchCreator passes partition columns as though they are physical columns and this
causes drill to raise the exception below:
> {code}
> Failure while running fragment., You tried to do a batch data read operation when you
were in a state of STOP.  You can only do this type of operation when you are in a state of
> {code}
> The fix is to make sure that we are passing physical columns to the reader.
